The utility model relates to a novel high frequency high pressure single transformer core annular transformer which comprises an upper portion oil injection box, a secondary side coil, a primary side and secondary side insulating layer, a lower portion oil injection box, a high frequency magnetic core and a primary side wire, wherein the upper portion oil injection box and the lower portion oil injection box are respectively installed at the top and the bottom of the high frequency magnetic core. The primary side wire is arranged on the high frequency magnetic core in a winding mode and penetrates outside the upper portion oil injection box. The primary side and secondary side insulating layer is arranged on the high frequency magnetic core in a winding mode. The secondary side coil is arranged on the primary side and secondary side insulating layer in a winding mode. Two sides of the high frequency magnetic core are respectively provided with a annular oil channel in a sticking mode. The novel high frequency high pressure single transformer core annular transformer has the numerous advantages of being simple in structure, good in heat dissipation effect and the like.
Description
[technical field]
The utility model relates to a kind of transformer, is specifically related to a kind of novel high-frequency high pressure list device core toroidal transformer, and it belongs to electrical equipment technical field applicable to the high frequency transformer of 10～100kV, 16kHz～40kHz.
[background technology]
Traditional high-frequency and high-voltage toroidal transformer series-parallel modes of several device cores that adopt increase area of dissipation more.Current－carrying conductor expands because the load current heating makes transformer oil, and proportion reduces and moves upward, and the cold oil of fuel tank bottom is filled up the parital vacuum that deep fat rises and stays immediately, forms a heating and cool cycles around the device core.
Because traditional transformer is to utilize oil in device core outer loop, thereby can only heat be taken away from the device wicking surface, and the iron core of device core inner and former limit wire almost do not pass through thermal convection, heat can't effectively shed, cause transformer temperature to continue to raise, and the larger transformer temperature rise of the capacity of transformer is higher, causes the transformer radiating effect bad.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved high-frequency and high-voltage list device core toroidal transformer that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of high-frequency and high-voltage list device core toroidal transformer of simple in structure, good heat dissipation effect.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of novel high-frequency high pressure list device core toroidal transformer, and it comprises top oiling box, secondary winding, former limit and secondary insulating barrier, bottom oiling box, high frequency magnetic core and former limit wire; Wherein, described top oiling box and bottom oiling box are installed in respectively top and the bottom of high frequency magnetic core; Described former limit wire is wound on the high-frequency core and passes top oiling box; Described former limit and secondary insulating barrier are wound on the high frequency magnetic core; Described secondary winding technique is on former limit and secondary insulating barrier; The both sides of described high frequency magnetic core are pasted with respectively ring shaped oil passage.
Novel high-frequency high pressure list device core toroidal transformer of the present utility model further is set to: described ring shaped oil passage is formed by annular insulating paper.
Compared with prior art, the utlity model has following beneficial effect: novel high-frequency high pressure list device core toroidal transformer of the present utility model is with a plurality of device wicking surface of tradition radiating mode, change the mode that is increased oiling box and ring shaped oil passage by single device core into, force most of deep fat through oiling box and ring shaped oil passage the heat of high frequency magnetic core and former limit wire to be taken away, and because the oiling box is to install up and down, make the cold oil of fuel tank bottom force to carry out heat exchange through high frequency magnetic core and former limit wire, so its radiating effect is improved significantly.

Fig. 1 is the front view of novel high-frequency high pressure list device core toroidal transformer of the present utility model.
Fig. 2 is the oily flow diagram of novel high-frequency high pressure list device core toroidal transformer of the present utility model.
[embodiment]
See also shown in Figure of description 1 and the accompanying drawing 2, the utility model is a kind of novel high-frequency high pressure list device core toroidal transformer, and it is comprised of several parts such as top oiling box 1, secondary winding 2, former limit and secondary insulating barrier 3, bottom oiling box 4, high frequency magnetic core 5 and former limit wires 6.
Wherein, described top oiling box 1 and bottom oiling box 4 are installed in respectively top and the bottom of high frequency magnetic core 5, and fix with insulating paper.Described former limit wire 6 is wound on the high-frequency core 5 and passes top oiling box 1.Described former limit and secondary insulating barrier 3 are wound on the high frequency magnetic core 5.Described secondary winding 2 is being wound on former limit and the secondary insulating barrier 3 behind the former limit of coiling and the secondary insulating barrier 3.The both sides of described high frequency magnetic core 5 are pasted with respectively ring shaped oil passage 9, and this ring shaped oil passage 9 is formed by annular insulating paper, can flow through cold oil stream 7 in it.
During novel high-frequency high pressure list device core toroidal transformer work of the present utility model, because making transformer oil, the load current heating expands, proportion reduces and moves upward, the parital vacuum that the cold oil of high frequency magnetic core 5 bottoms rises immediately and stays, some cold oil can flow through the ring shaped oil passage 9 that sticks on the high frequency magnetic core 5 by bottom oiling box 4, arrive top of oil-tank by top oiling box 1 again, through after 8 coolings of device core outer loop oil stream, getting back to the fuel tank bottom, consist of a heating and cool cycles.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection range of this creation.
